An Ex-Blizzard Entertainment employee who worked in the StarCraft II QA team informed Blizzplanet that he launched two auctions in eBay featuring one-of-a-kind concept art signed by Glenn Rane and Brian Huang.

A third concept art of a Thor & Vulture signed by Mr. Jack is a copy of only 70 printed for the QA team members.

Auctions for each concept art range from $1,999.99 to a jaw-dropping $12,999.99.
